To ALL WHoM iT MAY coNcnRN:

Be it known that I, SAMUEL L. POTTER, of Wyandotte, in theY county ofWayne, and State of Michigan, have invented a new and improved RailPile; and `I do hereby declare that the following isa full, clear, andexact description thereof, which will enable those skilled in the art tomake and use thc same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 represents atransverse section of my improvedpile or fa-ggot, onehalf the actualsize.

Figure 2 is a transverse section of the same, illustrating a manner ofapplying old railroad hars in place of the inner or intermediate ironbars of the pile.

Figure 3 represents a trahsversel section of the 'complete rail, fullsize.

Similar letters of reference indicate corresponding parts.

The subject ot' this inventionis a peculiar arrangement of iron bars, inconnection With-a steel head of T form, the bottom of which steel headwill be protected from undueheatiug, and the Whole being adapted to bee'ectually welded together in the operation of rolling. I

In iig. 1, a pile is shown, composed of three at iron bars,b, of equaldimensions, (seven by one anda quarter inches,) placed one on the topof. the other, and 'four narrower bars, a, two 'and a halt` by one inch,placedr on thetop bar b, the outer edges ofthe bars a being placed ushwith the outer edges of the bars so that a space will be allowed betweenthem to receive 'the lower part cvof a T-'shaped steel bar; c e', saidpart c beingtwol inches square in its transverse section, and the upperpart c seven inches in width and one and three-quarters inch inthickness, the part c extending the whole Width of the pile. This' pile,when rolled, will produce a rail as shown in iig. 3, A being the steelhead and B the iron neck and base. By this means it will be seen-that nthe steel will be brought to awelding heat, and fully protected by the.viron, asthe steelwill Weld at a much lower heat than the iron, and thetwo metals will,V during the process of rolling, be perfectly weldedtogether.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is A pile or faggot for r'ailroadbars, constituted of iron and steel bars, arranged Asubstantially asherein represented and described.

To the above specification of my improved rail pile I have signed myhand ths`8th of November, 1855.

SAMUEL L. POTTER.
